2.2.2 Card In Event Keystrokes
The Card In event defines a generic keystroke header that is sent upfront of any card data.
This header is sent upon detection of the selected card type even when no card data is
selected in configuration.
2.2.3 Card Data Types
5x27 CK supports preset and custom data fields in Keyboard Wedge mode.
2.2.3.1 Preset Data Fields
Preset data fields represent the cards pre-configured data objects and for the 5x27 CK those
are the PACS-Bits and CSN. Memory area, key configuration is preset in the 5x27 CK;
therefore, no configuration is required to access those data fields.
PACS-Bits. The Physical Access Control System (PACS)-Bits are the data which grant
access to a facility.
Note: PACS-Bits are only available for cards containing HID physical access credentials.
Included are iCLASS Seos, HID Prox, iCLASS SE/ iCLASS SR, MIFARE (iCLASS SE)
and DESFire EV1 (iCLASS SE).
iCLASS SE/ iCLASS SR credentials require firmware 02000000. iCLASS Seos credentials
require firmware 03000000.
CSN. The Card Serial Number (CSN) is a data string which identifies your card uniquely.
Note: CSN is not available for HID Prox cards, since those cards do not provide an
additional unique serial number besides PACS-bits.
2.2.3.2 Custom Data Fields
Custom data fields allow access to custom data stored anywhere in the card user memory.
Therefore, configure the custom data field address + length and the access key prior to use.
Memory structure, naming conventions and security measures are specific to card type, the
web interfaces presents the required configuration input for the selected card type.
Note: For retrieving custom data, ensure the corresponding access keys are available in the
OMNIKEY 5x27 CK. Enter key references using decimal in the keyboard wedge configuration
interface.
See the Software Developer Guide, Chapter 9 for key loading details.

Note: Offset and data length are defined as BYTE. In the following example OFFSET = 1,
shifts the read zone by one byte and limits it to one byte:
Data on card (4 bytes total)
HEX 12345678
BIN 0001 0010 0011 0100 0101 0110 0111 1000
Output with OFFSET = 1, LENGTH = 1
HEX 34
BIN 0011 0100
